Snow Goose Beak and Tomia
If I had thought about the answer to that question when I was five, I would have said yes, most definitely. At that time, our family was living on a lake in north central Florida. A friend’s unruly pet goose chased me home, nipping my bottom all the way to our front stoop!
The jagged points in the serrated-edge jaw of the Snow Goose are not called teeth because teeth are defined as having an enamel coating. There is a special word for the points and they are called tomia. During the Mesozoic era birds had teeth. Over time, birds developed specialized beaks suited to their diets. Bird beaks do the job teeth and lips once did. The Snow Goose’s tomia are not as tough as teeth but are perfectly suited to slicing through slippery grass.
The super graphic below, found on wiki, illustrates types of beaks and how the different shapes relate to the bird’s diet and foraging habits.
